Hey, leave my OCD out of it! :)

Assuming you have a point above (not sure you do, but let's assume),
having 1 out of 13, and arguably one of the lesser-provisioned of the 13
at that, not subject to the DOS is of dubious value, for a variety of
reasons that I can elaborate if desired. It would make more sense if
only say half the roots were serving ARPA.
